Brazilian limeade popsicles

Put the sliced limes, sweetened condensed milk, sugar and ice water into the blender.

Blend on high speed for 15 seconds, no more, or the limeade becomes bitter.

Strain out all the citrus particulate and pour into the molds; normally this is served over ice instead.

Freeze at least four hours, ideally overnight.

These settle a little in the freezer, which guar gum would prevent.
